The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oatmeal
Provides the bulk and structure that holds the cakes together.
Treacle
Adds sweetness, moisture, and a dark colour, and helps bind the mixture.
Brown sugar
Adds sweetness and moisture, and deepens the flavour.
Melted butter
Adds fat for richness and a softer texture.
Powdered ginger
Adds warm spice aroma and flavour.

The step that matters

Let it rest for 24 hours. Resting lets the oats absorb the treacle and melted butter evenly, so the mixture firms up and holds its shape when shaped into cakes.

Swap the ginger

How well each one fits the dish's main ingredients (sugar, butter):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Gingerthe original
  4. Capersfits less well

Fit is the average pairing score against sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
